摘要：
When the picosecond pulse with a initial temporal modulation propagates and amplifies in the large-scale Nd:glass laser system, the temporal modulation will be accumulated and enhanced, which causes serious temporal distortion in the output picosecond pulse. The output beam quality of the whole Nd:glass laser system will become very poor due to the spatiotemporal coupling effect. So measuring the initial temporal structure and temporal evolutions of the picosecond pulse after nonlinear propagation is necessary. We propose a method of measuring ...
